Evolve 3

  1. 1. Genus: Homo
  2. 2. Family tree Homo habilis Homo ergastger Homo erectus Homo heidelbergensis homo neanderthalensis Modern homo sapiens
  3. 3. Homo habilis <ul><li>brain: 610-750 cc. (compare with average of 1350 for modern humans) </li></ul><ul><li>2.3-1.7 mya </li></ul><ul><li>used simple Oldowan stone tool-kit – because of limited brain and/or manual dexterity development </li></ul>
  4. 4. Homo ergaster <ul><li>approx. 1.8-1.0 mya </li></ul>
  5. 5. homo ergaster <ul><li>brain: some skulls measure 870 cc – some possibly more than 900 cc </li></ul><ul><li>More advanced Acheulean technology </li></ul><ul><li>Moved north to cold climates, possibly wore clothing. </li></ul>
  6. 6. Homo erectus <ul><li>approx. 1.15 mya- 27,000 ya (maybe) </li></ul><ul><li>Brain: avg. about 1000 cc </li></ul><ul><li>Still Acheulean tool kit. </li></ul><ul><li>but… </li></ul>
  7. 7. Homo erectus <ul><li>They were wide-spread – all across the old world, possibly even able to build boats to travel sort distances to coastal islands. </li></ul>
  8. 8. Homo Hiedelbergensis (Archaic homo sapiens) <ul><li>Evolved out of homo erectus about 650,000 ya, lasted until they spawned and were replaced by neanderthals first, then modern humans about 100,000 ya </li></ul><ul><li>Brain size: close to modern size, 1100cc – 1200cc avg. </li></ul>
  9. 9. Archaic homo sapiens <ul><li>Range: all over the old world (no evidence in new). </li></ul><ul><li>Much like modern humans, different facial features. </li></ul>
  10. 10. Neanderthals <ul><li>From approx, 130,000 ya-possibly 28,000 ya. (Very recent) </li></ul><ul><li>Short, stocky build, flattened head, longer in the back. Their eyes were up higher than ours are. </li></ul>
  11. 11. Neanderthals <ul><li>Brain: Some say slightly smaller than ours, others put the average at about 1400 cc, or slightly larger than modern humans’. </li></ul><ul><li>Mousterian tools. Didn’t adapt as easily to more sophisticated tools – possible cause for extinction when in competition with modern humans. </li></ul>
  12. 12. Modern homo sapiens <ul><li>Emerged between 100,000-50,000 years ago </li></ul><ul><li>Full sized 1200-1800 cc brains. Avg. 1350 </li></ul><ul><li>Mousterian tools -> Cro-Magnon tools (upper paleolithic) -> planes trains and automobiles. </li></ul>
